WE WANT TO KNOW IT ONCE FOR ALL: RBs VS JZs

[GTRSTILL]

JZ..

Stronger stock and cheaper to tune. Which means more pennies in the young lads pockets to put to good use... like getting laid and buying houses.

If it's just an engine thing I guess the toyota motor has it.
However for me it's the package, and my love of skylines is not blind.
I can make a M3 beater from a gts-t for say 3-4k in every department road drag track reliability.
I love R33 hicas it flatters me and stops me spinning often.
My car now on 3rd re-build is VERY fit, but the dynamics of the whole thing make it a GREAT GT a-to-b A and b road monster tool.
I know where I like sitting.

Well my JZX81 has a RB26 under the bonnet!



All I need now is a 4door R32 with a 2JZ under the bonnet and ill be set

[Thrust]

Holy Mackerel! Any piccies of the car?

"All I need now is a 4door R32 with a 2JZ under the bonnet and ill be set" You mean like two of them, but neither what they seem? Guys in knickers and gals in jockstraps............... Nuts in extremis!!!

And...Ghost Dancer? The guy up the road from me over there in Okayama?

PS Anyway, GTRLux, how can you expect impartiality on a GTR site? :headbang:

[SteveN]

Thrust- here you go

[gtrlux]

SteveN, is that what you working on between the late night clubs, late night pubs and the simply very late nights
Looks awsome mate.
The Blit I refered to, is the last version, goes like hell, got smoked a few times in a Legacy B4 out of a Highway toll gate by thoses Blits . . . sad they look so conservative. . .

[Thrust]

SteveN. Very nice! Thanks for the piccie!!!

[NIGHTRIDER]

Both great engines, however..


..look at the amount of MKIV (JZA80) Supras that have appeared in the classifieds with 100k+ miles on the clock and are still going strong, many without having had engine rebuilds. Even modified examples can run to silly mileages without any major problems if looked after properly. Plus, a lot of these cars will have been used as daily drivers as well.

In comparison, RB engines are more than capable of 6 figure mileages. In reality, a Skyline (GTR especially) with 80k miles is considered as a relative high-miler and even if lightly modified, will probably have had an engine refresh/rebuild at some point. I was told by a VERY reliable source that, rule of thumb, 60k was a good time for an engine refresh for an R33 GTR.

I notice gearboxes being mentioned previously in this thread. The 5-speed manual gearbox was only used in the N/A (SZ) Supra variants. The 6-speed manual gearbox in the Supra is bombproof, pretty much like all Toyota gearboxes. Even the auto transmission used in the JZA80 is known to handle up to 600bhp.

In 1993, the Supra Turbo had a 5-speed, it was upgraded to a 6sp shortly after I think.

JZ for me too.

I've had 2 skylines (32 & 34, 3 skyline engines - stock rb26, nur rb26 and Top Secret RB28) and 2 Supras (600bhp Modded HKS TO4R Auto- with stock JZ and Stock UK TT 6 Speed) and have to say as an engine and an overall package the Supra wins for me everytime!!

It's a great deal more reliable, my HKS car had 80,000 miles when I sold and still going very strong, had been running 1.4-1.5bar on a T04R for ages without any problems at all. Much cheaper to modify, and the engine is much better specced from the factory, don't have to start uprating sump/oil pump/water pump etc etc.

Dare I say it, its far more challenging and enjoyable to drive imho too.

And I just missed out on a stunning T51R supra from Japan last week dammit

Not the MKIV JZA80 model. It was the previous JZA70 turbo model which used a 5-speed gearbox, with the earlier 1JZ engine. There was never a (production) RZ made by Toyota with a 5-speed gearbox.

[R33_GTS-t]

Out of interest, do RB26 heads flow better or worse than 2JZ heads.

I got confused because of 2JZ-GTE transplants into non-turbo models.




Folks check this thread out:

Stock internals arn't so bad after all 630whp proof

[AmGT-R]

Take out the 4wd from the GT-R and you'll have nothing. What makes a GT-R amazing is the whole car from top to bottom.

But as for engines; its the 2JZ without a doubt, I broke 3 RB26s and the 2JZ is still yawning whenever I kick it around.

cheers.

[tokes]

If I could have had a MKIV I would, but the turbo MKIV's still are fetching 45+ thousand dollars here.

So I had to "settle" for a GTR, it's a pain in the ass to have to do oil pump/water pump/oil pan/cylinder head mods just to make it to 600 HP, and then worrying my ass off about breaking a transmission or front diff.

I'd love to have a 2JZ mated to an AWD Getrag V160 in a Skyline GTR body. Yum
